The carbine retains the early Type I barrel band without a bayonet lug and a two-rivet walnut handguard, illustrating the mid-war configuration before later upgrades. An arsenal-installed stamped Type II rear sight reflects common post-war refurbishment practices while maintaining field utility.
The parkerized gray phosphate finish remains uniform, complementing the original walnut stock. At 17.75 inches, the barrel maintains the correct wartime length for the platform and is chambered for the .30 Carbine cartridge, feeding from the included 15-round magazine.
Operating on the standard short-stroke gas piston system, this semi-automatic carbine offers the quick-handling characteristics that made the design a mainstay for U.S. forces. With its scarce IBM production, matched IBM components, and 1944 provenance, this rifle stands out as a collectible yet shootable example of America’s WWII small-arms history.
